LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed September 12, 1918. Serial 1V0. 253,787.

To all whom it may concern:

Be it known that I, DAVID ELMER Roe- ERTS, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented a certain new and useful Improvement in Lighting-Fix tures, of which the following is a specification.

My invention relates to that class of de- Vices which are designed to utilize stock parts, and to produce a simple and inexpensive semi-indirect unit which will be efiicient.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawing, which is hereunto annexed and is a part of this specification, in which:

Figure 1 is a side elevation of a lighting fixture embodying my improvement.

Figs. 2 and 3 are enlarged fragmentary detail views of the supporting means.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawing, the lighting fixture comprises a canopy or suitable ceiling support 4:, from which depends a chain 5, to a holder 6. This holder is provided with a collar 7, provided with set screws 8, which are adapted to engage the neck 9, of a fiat opal shade or reflector 10. The electric light bulb 11, is mounted in a socket 12, secured in the holder 6, and the filament of the lamp bulb 11, extends into a shield or bowl 13. This bowl is supported by my improved holder 14, which comprises a ring, which is formed of a plurality of sections, 15, 16 and 17. As illustrated, it is provided with'three sections, though it is obvious that it can be made of any desired number. The adjacent ends 18 and 19, of the sections are entwined together,

and terminate in hooks 20, which are.adapted to engage the periphery of the flat opal reflector 10.

Inasmuch as the material of which the bowl supporting ring is formed is of resllient material, there is suflicient spring in the ends 18, and 19, so as to clamp the periphery of the shade firmly. They belng made of smaller diameter than the diam- .eter of the shade necessitates their being sprung outwardly to enable them to engage the edge of the shade, and the resiliency of the material causes them to clamp it firmly.

It is apparent from the foregoing descrip tion and an inspection of the drawing, that a my device provides a shadowless fixture, in which the engagement of the bowl with the reflector is entirely automatic, and does not require any adjustment. Consequently the fixture can be assembled without the use of a skilled electrician or lighting fixture mechanic.

Having described my invention what I regard as new and desire to secure by Letters Patent of the United States, is:

1. In a lighting fixture, the combination of a holder with a fiat opal reflector, a bowl below said reflector, bowl supporting means comprising a ring formed of a plurality of sections, the ends of said sections being bent upwardly and entwined together, the ends terminating in hooks which engage the periphery of the reflector.

2. In a lighting fixture, the combination of a holder with a flat opal reflector, a bowl below said reflector, bowl supporting means comprising a ring formed of a plurality of sections, the ends of said sections being bent upwardly and entwined together, the ends terminating in hooks which engage the periphery of the reflector, said ring and sections being formed of resilient material.

In testimony whereof, I have signed the foregoing specification.
